GOVER-ATTACI-IING MEANS FOR BOOKS. 1,423,018 specification of LettersPatent. Patentgd July 18 1922,

Application filed September 19, 1921. Serial No. 501,527.

To all whom it may concern:

Be it known that I, IVILLIAM P. PITT, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented a certain new and useful Improvement in Cover-AttachingMeans for Books, of which the following is a specification.

My invention relates to improvements in loose leaf books.

It relates particularly to a novel means.

for attaching the metal parts to the back of a loose leaf book.

The object of my invention is to provide novel means for attaching metalparts to the back of a loose leaf book which is sim ple of construction,cheap to make, strong and durable and not liable to get out of order,which permits of the ready assembling and removal of the metal parts,and which presents a good appearance.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawing which illustrates the preferred embodimentof my invention,

Fig. 1 is a perspective view, partly broken away of a loose leaf ringbook provided with my improved fastening means.

Fig. 2 is a top view, partly broken away, of the covers and back, thelatter having sewed to it a flexible strip which forms with the back apocket in which is shown a back plate, one of the free ends of the stripbeing shown underlapping the back plate, and the other end of the stripbeing shown stretched out.

Fig. 3 is a lon itudinal sectional view on the line 3-3 of ig. 2.

Fig. 4 is an enlarged cross section on the line 4-4 of Fig. 1.

Similar reference characters designate similar parts in the differentviews.

1 designates the back of a loose leaf book, 2 the covers thereof and 3longitudinal grooves in the inner side and at the longitudinal edges ofthe back.

4 designates a tape or strip of flexible material, such as cloth, whichis disposed longitudinally on the inner side of the back 1, and which isfastened adjacent to its longitudinal edges, in any suitable manner, asby being sewed by stitches 5, to the back 1 adjacent to the longitudinaledges of the back and between the grooves 3. The strip 4 forms with theback a pocket having open ends, and adapted to receive therein a metalback plate 6.

The strip 4 has free ends adapted to be folded so as to underlap theends respectively of the back plate 6, as shown at the left in Figs. 2and 8. The underlapping ends 7 of the strip 4 serve to cover the ends ofthe back plate and to hold the latter in the pocket.

8 designates an arcuate spring plate which rests upon the strip 4 and isadapted to have its ends overlapped by prongs 9 which extend upwardlyfrom. the back plate through the strip 4.

The spring plate 8 supports the usual hook plates 10, which areinterlocked at their inner edges and have co-op'erating hooks 11.

Pins 12 extend through the back plate 6, and strip 4 and are adapted tobear against the under sides of the hook plates for swinging the latterto the open position when the pins 12 are pressed inwardly.

In assembling the parts, the back plate 6 is first inserted in thepocket between the strip 4 and back 1, the prongs 9 being extendedthrough the strip 4 and spring plate 8, the inner ends of the prongsbeing bent over the spring plate, thus holding the latter to the backplate 6. The free ends 7 of the strip 4 are then folded under the endsof the back plate 6, thereby holding the latter securely in operativeposition.

I do not limit my invention. to the structure shown and described, asmodifications within the scope of the appended claims, may be madewithout departing from the spirit of my invention.

IVhat I claim. is

1. In a loose leaf book; of the kind described, a back of a book, and astrip of flexible material sewed adjacent to its longitudinal edges tothe back and adapted to form therewith a pocket for receiving a backplate, and having free ends adapted to underlap the ends of the backplate, substantially as set forth.

2. In a loose leaf book of the kind described, a back of a book havingtwo longitudinal grooves, a strip of flexible material fastened adjacentto its longitudinal edges to the inner side of the back and formingtherewith a pocket intermediate of said grooves, and having free ends,and a back 45. In a loose leaf book of the kind described, a back of abook, a strip of flexible material fastened adjacent to its longitudinaledges to the inner side of the back adjacent to the longitudinal edgesof the latter and forming therewith a pocket, and a back plate in saidpocket, the strip having free ends which respectively underlap the endsof the back plate, substantially as set forth.

In testimony whereof I have signed my name to this specification.

WVILLIAM P. TPITT.
